Here’s one thing you should always have in mind when planning a trip: money. That means you need to plan how much you’re going to spend and know the paying methods that will be available for you in your destination. Some questions you need to answer: What’s the currency of the country? Do I need to convert my money? What is the currency conversion? Where can I find the nearest ATM? Does the hotel accept credit or debit cards? What is the cost of the tickets to the attractions that I want to go? How much my bank charges for international transactions?
All these questions will help you define how much money you will need (there are some websites that can help you plan how much you will need for food and essentials) and how much money you should bring with you in cash.
